Introduction to computer

The d word computer is derived from the word computer, which  means calculation. Then  In  colloquial language it is considered as a calculating device that can do arithmetic and lo1 Types of computer

gical operations with speed, but today  and

 

logical with compute is not limited to calculation today it is used  for

Changes into information and presents the output  resulted it accepts stores and manipulates data according to our need.

1 Types of computer

 

Characteristics of computer   and likely to be defined or tell the capability of compute .

 

Speed..

Computers. Can carry out  instructions in less than a millionth of a second  .

As you  know computers can we our very fast., 1 Types of computer In  takes only few second for calculations that we take hours to  instructions and even more per second.

Accuracy..

Computers can do the do the calculations without errors and d very accurately.

 The de grief accuracy of computer is very high and every calculations is performed with the same accuracy. The errors in computer are due to    human and l inaccurate  data.

Diligence;

 

Computers are capable of performing any task given to them repetitively.
